Extra long 3mm dia drill bit req

[mart]

Does anyone know if it is possible to obtain a 3mm dia drill bit that is 125mm long (only going through soft material)? The longest I have seen at T Station is 100mm. The material that I am drilling is 100mm long and I imagine that I need 25 mm of the shank to be in the drill chuck. Not found any on flea bay.

Cable Ties Direct hold a range of unusual drill bits, may be worth a try.

I've turned down the shank and pressed on a drilled extension before, to get out of the crap.

I have welded drills to things before, always worked OK.
Drill service will have one if you want to buy one.
